OBJECTIVE: While there are well-established guidelines for optimum video-EEG monitoring (VEM), the process of reviewing VEM data varies amongst centres. In this study, we compared continuous with sampled reviewing of VEM data to assess whether their diagnostic yield differs. METHODS: VEM data acquired from 50 consecutive patients (31 females) admitted for VEM were reviewed by two independent electroencephalographers, one using the continuous review method, and the other sampling the first five minutes of each hour together with events identified by push buttons and automated spike detection software. Overall agreement between reviewers was calculated using the Kappa statistic. Comparison bet..View full abstract
